Consider the example of [5, 2, 3, 1, 0], following the scheme, after the first partition the array becomes [0, 2, 1, 3, 5], the "index" returned is 2, which is the number 1, when the real pivot, the one we chose to start the partition with was the number 3. With this example, we see how it is necessary to include the returned index of the ...

This is known as the Lomuto partition scheme, which is simpler but less efficient than Hoare's original partition scheme. In quicksort, we recursively sort both branches, leading to best-case () time. However, when doing selection, we already know which partition our desired element lies in, since the pivot is in its final sorted position ...
Multi-key quicksort, also known as three-way radix quicksort, [1] is an algorithm for sorting strings.This hybrid of quicksort and radix sort was originally suggested by P. Shackleton, as reported in one of C.A.R. Hoare's seminal papers on quicksort; [2]: 14 its modern incarnation was developed by Jon Bentley and Robert Sedgewick in the mid-1990s. [3]
While the Quick Sort article gives people the view of the quick sort algorithm, we can update some new findings to it to make it stay up to the new research. For example, when changing the pick of pivots will improve the worst case of time complexity from O(N^2) to O(NlogN). MiaoQiQi 20:55, 14 March 2023 (UTC)
